The Pittsburgh Steelers are struggling in all phases offensively, from a ground game stuck in neutral to a passing attack slowed by constant pressure on quarterback Ben Roethlisberger.

Those struggles can be attributed to injuries to Maurkice Pouncey and Le'Veon Bell, or to the defection of wide receiver Mike Wallace. They can also be blamed on the absence of Heath Miller after the veteran missed the first two weeks with a knee injury.

Miller is back in the lineup and getting back to game speed. Can he help your fantasy football team?

Overview: Veteran tight end who made his season debut in Week 3 after offseason ACL surgery.

Background: Enters his ninth season after career-best numbers in yardage (816) and touchdowns (8) in 2012. … is a two-time Pro Bowler and an underrated key to the Steelers' struggling offense. … will play a limited number of snaps for the first handful of weeks until he gets back to full health.

2013 stats: 3 catches, 4 targets, 35 yards, 0 TDs

Numbers and trends: Got a career-high 101 targets in his first season under offensive coordinator Todd Haley. … has 39 career touchdowns with at least five TD catches in five of his eight seasons. … had at least four catches 11 times and at least 40 yards 13 times in 15 games last season.

Strengths: Looks like a staple in the Steelers' offensive scheme under Haley. … has a long track record of producing strong and consistent numbers. … with Steelers' undersized wide receivers, Miller can be an even more important red-zone target. … has No. 1 tight end potential if or when he returns to full health.

Risk factors: Still must take steps to make full recovery from December knee surgery. … Steelers offense is struggling badly, including along the offensive line, which could hamper Miller's production. … struggles of OTs Mike Adams and Marcus Gilbert have potential to add blocking responsibilities for Miller.

ESPN ownership: 13.0 percent.

Verdict: Isn't yet a TE2 option, but can get there quickly as he recovers; worth a speculative add in deep leagues now.
